China and Venezuela have pledged to phase out the use and production of chlorofluorocarbons (CFCs) by the end of 2007, two years earlier than required by the Montreal Protocol on Substances that Deplete the Ozone Layer.

As part of its commitment by Montreal Protocol concerning the non-use of substances that cause ozone depletion, in the beginning of this year the ministry limited the use of chlorofluorocarbons by setting specific rations for the companies that use this substance.

The most common chemicals include chlorofluorocarbons (CFCs), halons and chlorine-based solvents that have been used for more than 30 years as refrigerants, cleaning agents, spray propellants, foams and fire extinguishers.
